SKIP.

Application iled June 18, 192i.

l5 Rue de la Station, Ougre'e, Liege, Belgium, have inventcdcertain new and useful Improvement-s in or Relating to Sk-ipsgand I do `hereby declare the following to'be a full, clear, and exact description of the invention, such as willgenable others skilled in the art to which it appertains to make and use'the same, reference being had to the accompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention 'relates to a skip for raising ores or coal and relates specificallyto the type which are pivotally mounted on a frame slidable between vertical guides and tipped at the points of charging and dis charging by means of rollers mounted on the skip which engage rails which are curved at said points.

In the known installations of this kind, the skip is prevented from swinging when travelling between the charging and discharging points by rollers mounted on it and travelling on suitable rails extending throughout the length of its path. Atleast two rails are required to prevent the swinging of the skip between the charging and discharging points, in addition to the two guide rails, thus bringing the number of rails up to four all of which extend the entire distance between thc charging and discharging points.

This invention has for its object to make it possible to utilize only two rails along the whole length.

To that end, the rails ypreventing the skip from turning between the charging and the discharging` points are dispensed with, and during the travel between the said points the skip is locked to the suspension frame by means of a suitable locking device which is unlocked when the skip is to be tipped, the tipping being produced by means of ad ditional rails provided only at the points where such tipping is to be effected.

Other characteristic features of the invention will appear from the following de"- scription of the accompanying drawings, and are'specially set forth in the claims. Y

The drawings show by way of example a construction according to the invention and Serial No. 478,689.

relate to a tipping device installedv at fthe framework sui-mounting theV vertical shaft.

In the said drawings: Y F igure l shows the skip which has reached ciose to the point where it is to be tipped.

Figure 2 shows the skip beginning its tipping movemnt.

Figure 3 shows the skip tippedf.

Figures 4 and rrelate specially to the locking'device.- x f A skipv 7 is pivoted aboutka'pin 9 provided attlielower partofthe frame l which is vsuspended'from a cable '2. This 4frame l 1s'guided'throughout the wholeof its travel meansr 'of 'rails engaged by two lchecks 4 and l0 of guides provided on the said frame. It should be noted that the turning aXis 9 is placedV outside the vertical plane which passes through the center of gravity of the bucketl in such a way that the bucket always has a tendency to move to a tilting l position, this tendency being controlled by means hereinafter brought out. The tipping of the skip 7 between the charging and discharging points is prevented in the following manner: The skip has at each side a block 8 engaging with the bottom of a thickened part ll of the frame l, which prevents its turning backwards. On the other hand, in front,y the block S strikes against the guide rail S, which prevents the turning forward.

Near thefpoint of tipping of the skip, thel rail 3 is broken from a to?) (Figure 5) so as to afford passage forward to the said' block 8.

Before the block 8 reaches the broken or open part L b of the rail 3, the rollers 5 provided on each side of the skip 7, engage the rails 6 so that the skip will be held in the desired position a-s soon as the block 8 has passed through the opening inthe rail 3. This movement of the blockS is controlledv by an angular movement given to the skip by the curvature of the rails 6 which guide the rollers 5. Figure 2 shows the position of the skip 7 soon after the block 8 has passed through the opening.

The ascent of the framey l continuing, the inclination of the skip will increase; at a given moment the runners 14 arrangedv at each side of the skip 7, will engage with rollers 15 arranged' at the end of the rails 6.

If the hoisting of the frame l continues, the- ANONYME OUGREE- skip resting on the rollers 15 h v means of its runners 14, will he raised in such a manner that its rollers 5 Will engage with the curved end of the rails 13 intended to guide the skip in the. event of the trame being raised too high.- Soon after the rollers 5 have engaged With the rails 13, the run ers 111 leave the rollers 15, and the skip is sup`V ported onlyY by its rollers 5 raveiling on the rails 13. y

It is obvious that during the the frame the various stages of turning follow eaeh other in the reverse sequence, so that when the traine 1 has been lowered to a suiiioient extent, the skip 7 occupies the position shown in Figure 1.

`What l Claim is:

1. In ay structure ot the character described, a' sliding` trame.. rails guiding slid ing movement ot said trame7 a receptacle pivoted to said frame, one of said rails heA ing provided with a. cutout intermediate its length7 guides extending from said rails adjacent the cutout, a stop for preventing descent ot tipping or dumping ot the receptacle Carried by said receptacle and engaging said broken rail and movable through the cutout thereof to permit dumping of said receptacle1 means carried hj.' si.` id ref-eptaele for engaging said guides and moving the receptacle to a dumping position Vwhen the stop'moves through the cutout of the rail7 and rails extending upwardly above said guides and adapted to he engaged bvthe guide engaging means after the receptacle has heen tilted and said means moved out of engagement Withthe guides.

2. The structure oit claim 1 and arms extending from the reeeptaele'tor engaging the guides and 'torming t'ulcrum means permitting tilting of the receptacle to bring the guide engaging means ot' the receptacle' into position tor engaging the upwardly entending rails. Y

ln testimony whereof l have signed my name to this specification. y
